The is made of concrete cast in a suitable mold or concrete rollers as will be appreciated may be form. For most purposes, the preferred dimenmade inany desired size with the bevel edges sions of each wheel or roller is 16" diameter and of the rim of any desired angularity and dimen- 55 sions. They may be assembled in any number as the condition may warrant on a shaft of any size, and will provide a land roller of great efiiciency and low cost.

Having thus described a preferred embodiment of my invention, without having attempted to set forth all the forms in which it may be made, or all the modes of its use, what I claim, and desire to secure by Letters Patent, is:-

l. A wheel for a land packer formed of reinforced concrete and comprising a cylindrical body portion having flat parallel sides, a V-shaped rim portion, a metallic bearing bushing embedded within and disposed axially of said wheel, a V- shaped metallic reinforcement arranged Within said rim portion in concentric relation with the sides thereof, a stiff wire ring disposed in the V of said metallic reinforcement, and a plurality of radially disposed rods connected at their inner ends to said bearing bushing and at their outer ends to said wire ring,

2. A concrete Wheel or roller comprising a body portion having flat parallel sides, a V-shaped rim portion, a metallic bearing bushing embedded within and disposed axially of said wheel or roller, the ends of said bushing terminating in the plane of said sides, and a V-shaped annular wire mesh reinforcement arranged within said rim portion with the inclined sides thereof disposed in substantial parallelism with the inclined sides of said V-shaped rim portion.

3. In the concrete Wheel or roller as set forth in claim 2, including a stiff wire ring disposed in the V of said wire mesh reinforcement.
